Ok, before the assembled crowd I do acknowledge my incipient leanings towards hoarding. And do acknowledge that when I was forgetful and didn't order new crush rings I have taken chances and after careful examination and consideration re-used the old one. Then recently on a ride/drop-by of my friend Greg's shop where I always examine the trash barrel for thrown away goodies, I was surprised to find at least 1 or 2 lbs of (I believe used) aluminum crush rings. I inquired - the trash barrel (actually a small cardboard box) is left out for metal collectors who routinely drop by and take away the metal. - and was told the hoard came from the bike shop next door and nothing was known about them. SOooo, naturally I appropriated them and put them in a plastic bag and took them home. Now in my defense Greg is known to have thrown away tools which he didn't want to bother fixing and bike parts. For instance I recently have acquired an extensible wrench and a handle bar mounted rear view mirror such as used on K bikes. All with permission.
Now with the crush rings home, I washed and examined them and threw out any that looked marginal. Think there's still at least a lb of them left. What is the sense of the assembled intelligences on their use? I remember a discussion years ago on another website where certain types of washers/crush rings needed to be reheated and allowed to cool to remove work hardening. Does this apply to aluminum rings? Any issues to be considered?
